Looks like Newspaper them is not compatible with WordPress 6.9 (using 100% CPU)

Today, I upgraded to WordPress 6.9.

However, as soon as I began editing and creating posts in the admin area, the CPU on the server started to show 100% usage. RAM usage also went through the roof.

After looking into the issue, checking online on other websites like this thread on Reddit, this looks like a theme compatibility issue.

I disabled as many plugins as I could, but of no use. Please look into the matter, and what’s your ETA on a 6.9 update fix?

Thanks.

The ‘System Status’ page is also not opening in WordPress 6.9.

It’s only showing a blank page with a couple of links. Not loading information.

A *lot* of plugins are not compatible (yet) with WP 6.9 – Yoast, WooCommerce, Elementor all had to do emergency updates – one plug I rely on, FeedWordPress generates error trying to run. WP 6.9 changed some core code, which breaks a *lot* of stuff.

I rolled back to 6.8x on five sites to ensure they work.
(I don’t work here.)

For now,

I have reverted to WordPress 6.8.3.

The Theme Panel, where it shows System Status, did have issues with 6.9. It wasn’t loading or showing any information.

6.9 is also not compatible with Cloudflare plugin. Also as soon as I started a new post or began editing, the CPU and RAM usage reached its max and website went down. Creating/editing a post became a headache.

You also need to increase your WP Memory Limit and Max Vars for WordPress 6.9 to function properly, especially on the backend/admin.

Hope this helps someone.
